What is CVE-2026-85972?

Progress MarkLogic Server versions prior to 12.1.0 (12.x) and 11.3.7 (11.x) expose a vulnerability in their Kerberos authentication process. This vulnerability stems from inadequate verification of the identity of the Kerberos authentication service, particularly in password-based configurations. As a result, a network-positioned attacker could impersonate legitimate authentication services, leading to unauthorized access to sensitive information or modification of protected data, thereby posing a serious risk to data integrity and confidentiality.

Affected Version(s)

MarkLogic Server 11.0.0 < 11.3.7

MarkLogic Server 12.0.0 < 12.1.0
